Watch Conan O’Brien Sing ‘The Monorail Song’ from The Simpsons

Because you can never have enough Simpsons. Or Coco.

In case you missed it, talk-show host Conan O’Brien revisited his earlier days in the biz this weekend when he performed at the Hollywood Bowl’s celebration of all things The Simpsons.

Of the event’s many re-enactments of the hit show’s greatest moments, O’Brien finally gave fans what they’ve been craving for a very, very long time: “The Monorail Song” from the episode “Marge vs. The Monorail,” which he wrote more than 20 years ago.

O’Brien dressed up as Lyle Lanley for the performance, paid tribute to the late Simpsons alum Phil Hartman, and was backed by the Los Angeles Gay Mens’ Choir.

O’Brien said:

Yes, that episode has haunted me to this day. I’m very proud of it. It combines three things that I’m fascinated with: bad ideas for mass transit in the future, Irwin Allen disaster movies from the 1970s, and my favorite musical of all time, The Music Man. It all came together in one episode that’s haunted me to this day. I can’t go anywhere! I can’t go anywhere after 21 years in front of the camera without someone coming out of the crowd, looking around, and going, “Monorail Maaan…”

OK then. Here it is, Conan O’Brien singing “The Monorail Song.” Finally.
